Taking the time span from the late 1990s to the 2010s as a time span, it writes about how a generation of people rose rapidly in the dividends of the times, and how they were trapped by the "floating building" they built after owning it. A bright and stable grand mansion is built from the ruins of a generation. In the midsummer of Melbourne in 2024, sixteen-year-old Lu Yu has a perfect life that is envied by outsiders: a well-off family, loving parents, and growing up wrapped in favor and stability. Until a strange friend verified that everything was perfect - he had a half-sister, Lu Zhixia, who was nine years older out of thin air. In an instant, his sixteen years of carefree life were shattered. He is not the result of love, but the result of a precise calculation. The sunshine, dignity, wealth and exclusive favor he enjoyed were all based on the breakdown of another family, the departure of a first-mover mother, and the replacement of a girl's life. Underneath the bright youth of a foreign country, there are dark foreshadowings laid down by my parents in the 1990s.
Intent: The price of class jump: Ordinary people in the era are eager to escape fate and climb upward, but every shortcut choice will not disappear out of thin air, and the price will be passed on to the dearest one. The dignity gained by Lu Jingyi's pursuit of opportunities and ambitions was based on the sacrifices of others. Fake family perfection: Many "floating buildings" that appear to be happy and stable are based on lies and debts. Under the glossy shell, there are buried people and ignored pain. Intergenerational transmission of destiny: The decisions made by the previous generation out of ignorance, survival, and desire do not have to be repaid by the next generation, but the damage will be passed across time; the younger generation must face the mess left by their ancestors, discern the truth, complete self-salvation, and do not have to repeat the fate of the previous generation. The shades of human nature: There are no pure good guys and bad guys. Lu Jingyi, Song Wan, Su Huiyan and others are participants of the times, and they are also pawns trapped by the environment. Desire, weakness, survival, and obsession coexist in the same person. Truth and Reconciliation: Knowing the truth does not mean only revenge and destruction, but also includes seeing suffering, accepting brokenness, and finding one's own survival position amidst all the debts. All superficial prosperity has a hidden price; the choices of one generation shape the destiny of several generations.
